Arduino Using EEPROM

notsolowki:
i ran your example code but both times it printed the same thing on the console.

Probably the code ran once without you noticing (ie the serial console was not opened when you first uploaded)

notsolowki:
can you show me an example with an unsigned long please?

Well just put unsigned long in the structure...

struct __attribute__ ((packed)) _paramS {
  unsigned long minimumT;
  unsigned long maximumT;
} myParamters;

of course you need to adjust the values as you can't store -22 or -55 in an unsigned...

change the keyword to something else so that default values are written again
